LUT MixerManual

LUT Mixer lets you combine several LUTs and apply to an image simultaneously.

Load LUT

1 Loads a LUT from the hard drive or from another storage medium.

After loading the LUT it is saved in LUT Mixer. A subsequent edit of the

LUT or deletion of the LUT from your hard drive will therefore not cause any

changes in LUT Mixer. If a LUT has been edited on the storage medium would

have to be loaded into LUT Mixer once again, if this change is to be applied

to the project. Moving the project to another hard drive and changing the

paths to the original LUTs will subsequently also not result in a different look

in LUT Mixer.

Each instance of LUT Mixer loads its own LUTs which then will be saved

within this projects instance.

LUT intensity

2 Adjusts the intensity of the loaded LUTs. Depending on whether the

offset mode is set to “sum” or “average”, the intensity control can

respond differently. If the control is set to 0%, the LUT will not be taken into

account. A setting above 100% applies your LUT more intensely than it

actually is. Furthermore LUT 4 and 5 can also be applied negatively instead

of only positively. With a saturating LUT the plus-minus-control can for

example desaturate the image by applying the LUT negatively and LUTs that

warm up an image can now also be used to give the image a cooler look by

applying them negatively.

Sum

1 All LUTs for which the offset mode has been set to “sum” will be added

up. LUTs which push a specific color towards the same direction will

mutually reinforce each other while LUTs pushing similar colors into opposite

directions will mutually reduce each other.

Example 1LUT1 changes RGB 100/100/100 to 110/110/110 and LUT2 changes

100/100/100 to 105/105/105. The result from LUT1 at 100% and

LUT2 at 100% will be 115/115/115.

Example 2LUT1 changes RGB 100/100/100 to 110/110/110 and LUT2 changes

100/100/100 to 95/95/95. The result from LUT1 at 100% and LUT2

at 100% will be 105/105/105.

(Normalized) average

2 All LUTs for which the offset mode has been set to “average” will

proportionately be offset. Further, the cumulated overall intensity will

be normalized to 100%. The result will then be added to the LUTs which are

set to the sum mode.

NOTE! If only one LUT has been set to “average”, it will always be

added at 100% due to its normalization notwithstanding its selected

intensity. (This can be reduced or boosted with the master control

of the averaging group).

Deactivate (Mute)

1 Deactivates the respective LUT. If a LUT which has been set to

“average” is deactivated, the other LUTs which have been set to

“average” will be adjusted accordingly to achieve a combined value of 100%.

Solo

2 Deactivates all LUTs except the one set to “solo”. The “solo”-feature is

not a parameter in its own right. This feature merely changes the

“deactivate” parameters of all other LUTs. If you wish to use the solo key in

a keyframe animation, all deactivate parameters of all LUTs have to be

unlocked for the keyframe animation.

Deactivation of the “solo”-feature restores all Active-/Inactive-states of all

LUTs to what they were before activation of the “solo”-feature.

Master (average)

3 Since the added intensity of all LUTs set to “average” is always

normalized to 100%, the overall intensity of the average-group can be

reduced or boosted with this control.

ExampleThree LUTs which are set to average and which have the intensities

40%, 60% and 80% would - through the normalization of the

average-group - have the same result as if they had been set to

20%, 30% and 40%. In this respect, the overall effect can only be reduced

with the master-average-control and not by equally lowering all LUTs in

average-mode.

Master (All)

1 Reduces or boosts the effect of all LUTs summed in LUT Mixer (average

+ sum).

Skin Tones

Skin tones have an important role in color grading. In many cases,

a tint which appears good on the overall image can appear very

unnatural in combination with the human skin. Therefore, we have dedicated

a section to the skin tones to protect them from the tint of the LUTs and to

adjust them separately if necessary.

Protect Skin Tones

2 This control protects the skin tones from the influence of the LUTs. Up

to slider values of 50% the pure skin tones are protected. Depending

on lightening the skin can show highlights, which sometimes can belong (if

you determine the exact value) to the neutral tones. With settings over 50%

selected ranges of brightness in the neutral tones are protected from the

LUTs too.

Since the transitions between skin tone and non-skin tone in the

color space are often quite close to one another, artefacts can

quickly occur with highly compressed image material, depending on

the setting.

The skin tone controls make working with masks superfluous in

many cases. The better the quality of the source material, the better

the result.

Skin Tone Boost

1The „Boost Skin Tones“ control saturates or desaturates the skin tones

independently of the LUTs.

Skin Tone Hue

2 The „Skin Tone Hue“ control adjusts the skin color more to yellow or

more to red.
